WINDOW-SEAL? s am Application filed April 7, 1925. Serial No. 21,354.

This invention relates to window sealstrips, an object of the invention being to provide a strip which may be secured to the horizontal rail of one of a pair of slid ing sashes and which will be held against the glass or pane of the'other sashso as to close the opening between the sashes when one of the sashes is'raised and prevent thepassage of mosquitoes, flies and the like through the space between the sashes. p

In the use of ordinary screens, one of the sashes is moved, and usually the lower sash, so as to provide space for the screen below the same. When this is done an opening is left between the sashes through which mosquitoes, flies and the like enter the room, and it is the purpose of my in-' vention to provide a strip which is especially designed to be secured to the lower horizontal rail of the upper sash and which has a flexible strip elastically or resiliently held against the lower sash so as to effectually close the opening between the sashes and prevent entrance ,of mosquitoes, flies, etc.

With these and other objects in view, the

invention consists in certain novel features of construction and combinations and ar-' rangements of parts, which will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings-- Figure 1 is a view in longitudinal section through a pair of sliding sashes illustrating my improved strip in operative position, the view being taken in section on the line 11 of Figure 2;

Figure 2 is a fragmentary view in section on the line 2-2 of Figure 1.

1 represents a window frame having the ordinary upper and lower sliding sashes 2 and 3, respectively. '4; represents a screen placed in the window frame under the lower sash.

5 represents my improved window seal strip which is composed of spring metal,

forming a clamp 6 in which aflexible strip '7 is secured. Thisstrip 7 may be of rubber or any other analogous material and it is designed to engage the glass or pane8 of sash 3.

The metal portion of the strip 5 is so shaped asto provide an upwardly projecting flange 9 secured by tacks or other suitable securing devices 10 to the forward face of the lower horizontal rail 11 of upper sash 2. s 7

Betweenthe flange 9 and the clamp 6 the metal strip is bowed forwardly, as shown at 12, so as to provide a'spring which functions to press the flexible strip 7 against the glass Sand also functions to allow a certain bending action of the strip as a whole when the meeting rails of the sashes are brought together so as not to interfere with the closing of the window.

It will thus be noted that I not only provide a device which holds a flexible strip between the window sashes to close the opening between the sashes but I also provide resilient means constituting an integral portion of the metal strip which ensures proper engagement with the window pane and allows of a certain amount of movement to properly accommodate the device to its positionor positions.

The strip may be made in suitable lengths and the flexible strip 7 may be out as desired so as to exactly conform to the shape of the window sash with which it is to engage, as shown clearly inFigure 2.

Various slight changes and alterations 7 might be made in the general form of the parts described without departing from my invention and hence I do not limit myself to the precise details set forth but consider myself at liberty to make such slight changes and alterations as fairly fall with-- in the spirit and scope of the appended claims.

I claim:

1. A window seal strip, including a strip of spring metal having a clamp at its lower portion, a flexible strip secured in said clamp, said metal strip having an upwardly projecting flange adapted to be secured to a window sash, and said metal strip between the flange and the clamp body bowed forming a spring and holding the clamp portion normally spaced from the sash to which it is secured,

2. A strip of thecharacter described, comprising a metal strip and a flexible strip, 5 the metal strip bent upon itself at its lower edge forming a clamp in which the flexible strip is secured and at its upper portion bowed forwardly and then located in a straight line whereby the strip constitutes a spring or resilient member to exert pressure on the flexible stri and holding the clamp portion normally spaced from the sash to which it is secured:
